G10 – FR4 Machining – Epoxy Glass Laminates

G10-FR4 Machining

Firstly, the make up of G10-FR4 materials are an Epoxy Glass based Insulation Plastic. Laminates generally offer high mechanical strength and dimensional stability, are extremely durable, and maintain their properties wet or dry. Therefore the result of this blend is a material that offers excellent ark and track resistance.

The commonly known G10-FR4 are the most popular grades. G10-FR4 glass cloth reinforced epoxy natural is typically a yellowish to light green color. Epoxy resins are among the most versatile and widely used plastics in the electronics field, primarily because water absorption is virtually nil, rendering it an outstanding insulator.

As a result of being the most economic choice of G10-FR4 material, it is also noteworthy for being a material which can be easily machined to bespoke applications.

Some examples of what G10-FR4 Materials are widely used to manufacture are Insulating supports, high voltage insulation, bus bar supports and mounting panels in electrical apparatus are just some examples.

Based on the needs of its particular application it comes in several grades.

Most noteworthy, raw materials are available in standard sheets & rod sizes.

Finally a couple of important factors. Firstly Sheet thickness ranges from 0.8mm to 50mm.

Sentinel Plastic Engineering Only Supplies Bespoke Parts

All parts manufactured by Sentinel Plastics Ltd are customer specific bespoke plastic cutting parts. Either working from Prototypes, drawings, making a One off or hundreds of parts. Sentinel Plastics has flexibility to meet most requirements.

As well, the material is nearly immune to shrinkage, holding its form factor and dimensional stability at temperatures as high as 285° F. This property makes it ideal for use in electronic equipment with components that generate excessive heat. Should it combust at higher temperatures, the bromine added during the manufacturing process renders it self-extinguishing, another important factor for making its use in aerospace engineering so prominent.
